Benefits of technology

The patent text describes a new way to make articles that are resistant to wear and corrosion. The method involves coating the article with a layer of metal or ceramic material and then adding small particles made of diamond or cBN. These particles are coated with a protective layer of metal to make them stronger and more durable. The coated particles are then embedded within the layer of metal or ceramic material, making a composite coating that increases the lifespan of the article. The use of coated superabrasive particles in a wear-resistant coating has been found to increase the useful lifespan of articles compared to using uncoated particles.

Problems solved by technology

Common failure modes for these components typically include changes in dimensional form, development of pits, holes, grooves or other wear patterns that change the uniformity of a surface, and changes in tolerance that leads to inefficiencies in the performance of a component.

Comparison Between Coatings With Coated Diamond Particles and Uncoated Diamond Particles

[0053] As seen in FIGS. 1-4, a coating embodiment of the present invention wherein titanium-coated diamond particles are distributed within a glass matrix is compared to prior art coatings wherein uncoated diamond particles are contained within a glass matrix. FIGS. 1 and 2 represent a wear-resistant coating embodiment of the present invention wherein diamond particles of about 30 μm to about 40 μm are coated with titanium and deposited within a glass matrix material to form a wear-resistant coating. As illustrated by FIGS. 1 and 2, the glass matrix “wets” the surface of the coated diamond particles, as illustrated by the “textured” appearance of the coated particles within the glass matrix. This wetting in FIGS. 1 and 2 leads to better diamond particle adhesion and retention within the matrix. Thus an improved wear-resistant coating comprising coated diamond particles within a matrix material m...

Abstract

This invention is directed to a coated article having an increased useful lifespan, having a wear-resistant coating comprising a vitreous matrix material and metal coated superabrasive particles distributed therein. The superabrasive particles are coated with a protective metal coating selected from zinc, aluminum, aluminum-silicon alloy, titanium, chromium, nickel, silicon, tin, antimony, copper, iron, stainless steel, silver, alloys thereof, and mixtures thereof. The wear-resistant coating comprising coated superabrasive particles may be applied to the surface of an article by at least one process selected from electroless or electrolytic electroplating process, thermal spraying, and brazing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. provisional application Ser. No. 60 / 464,516, filed Apr. 22, 2003 and entitled “Method To Provide Wear-Resistant Coating and Related Coated Articles”, herein incorporated by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention relates to a coated article having a wear-resistant coating and an increased useful lifespan and a method of providing a wear-resistant coating to an article.
